My left turn signal is blinking fast. One night it was fast, then the next night it was slow, then the next night it was fast again. Now it’s fast all the time. I was going to just buy a cheap bulb to replace it, but then I happened to notice that it does light up (briefly, as expected) when I use my remote to lock the car. Any ideas of things that could cause that?
I haven’t tried to swap bulbs with the other side just yet, but will soon.
My Honda had a turn signal that would flash normally and then flash fast intermittently.
Turned out there was a bad connection at left front turn signal bulb socket.

Replace the bulb first, and not with anything cheap, then see what happens. Might want to replace the one on the other side as well if they’re the same age.
The door lock confirmation flash uses the parking/taillights, the turn signal uses a different, brighter filament in the bulb. The bulb likely has a burned-out filament (one of two inside the bulb).
Ahhhh very good to know, thank you. So at AutoZone, I see most of the Sylvania bulbs are around $8 but there is one for $18…There is one PEAK bulb in the 20’s and I don’t even know if the Diode Dynamics bulbs are relevant for my situation. Oh and there are LED’s as well. Since jdmere said don’t go cheap, I’m thinking the PEAK bulb since it’s not an LED? (I heard LED’s can melt things)
Syvania is fine. No need to overthink a turn signal bulb.

The basic Sylvania bulb is probably a higher quality bulb than the original, some manufactures use very cheap light bulbs. I have seen a lot of Kia/Hyundai vehicles with burned out light bulbs.
Another for replace the bulb that is out (not blinking when turn signal is on) with a Sylvania bulb…
Check the socket/wires for any burnt signs…
